FILLING MECHANISM.

Our invention relates to improvements in.

.filling mechanisms, and it consists in the combinatlons, constructions, and arrangements herein described and claimed. I In machinesiwhich fill bottles, that have a certain amount of air pressure therein, with a liquid, the air pressure increases With an equal rapidity to the increase of the liquid wi thin the bottles. 4

An object of our invention is to provide means for l/'eleawsing a desired amount of air pressure from a bottle at a predetermined point.

A further 'object of our invention is to provide a device of the type-described which can be ap lied to a machine for filling a plurality of ottles, and which has novel means for releasing any desired -amount of air pressure from each bottle at predetermined po- .20 sitions during the travel of the bottles as they are being filled with liquid.

A further ob'ect of our invention is to provide a device o the type described Which has adjustable means for releasing the pressure from the bottles at any desired position of the bottles in their travel.

Other objects and advantages Will appear in the followi specification, and the novel features of the mvention will be particularly pointed out in the appended claims.

Our invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a side elevation of the device as applied to a filling machine, I

Figure 2 is a enlarged sectional view of the device,

Figure 3 is a. section along the line 3--3 of Figure 2, and

Figure 4 is a modified form of the device.

In carrying out our invention, We make use of a liquid tank 1 having bottle-filling mechanisms 2 disposed therein. The filling mechanisms 2 are adapted to fill bottles 3 with liquid 4.

We provide an air pressure tank 5 upon which a Cover 6 is placedy and rigidly secured thereto. The cover is provided With an integral sleeve 7 extending upwardly therefrom. An annular recess 8 is cut in. the cover 6 at the lowermost part of the sleeve 7. The cover 6 also has an opening 9 disposed horizontally therein and in communication With the recess 8. A multiplicity of air passage- Ways 10 are disposed in a circuitous path withm the cover 6. A valve stem 11 is placed vvithin the sleeve 7 and moved upwardly unt1l an annular flange 12 abuts againstv a I leather seat 13. The valve stem `11l has an lntegral arm 14 extending at right angles therefrom and provided with an elongated opemng 15 therein. A tube 16, having a hose nipple 17 at one end thereof and an annular retanler tlange 18 at the other-'end thereof is placed Within the opening 15. A hard rubber seat 19 having an opening t-herein is disposed within the retainer flange 18. A compression spring 20 is disposed concentric With the tube 16 and is' held against the retained ilan'ge 18 by a nut 21. One end of a hose 22 rs placed upon the nipple 17. `A nippel 23 having a threaded shank is screwed into the arm 14. The opening Within the nipple 23 1s in communication With an opening 24 in the valve stem 11, and the opening 24 is-in communication with the annular recess 8. The free end of the hose 22 is placed upon the free end of the nipple 23 and both ends of the hose are rigidly held in place by Clamps' 25.

A ball bearing cup 26 is disposed concentric With the sleeve 7 and rests upon the cover 6. A ball bearing 27 is disposed Within the cup and is held in place bby a ball bearing cover 28. A compression spring 29 is placed concentric with the sleeve 7, the lower end thereof resting upon the ball bearing cover 28, and the upper end thereof abutting against an adjusting nut 30 'Which is held rigid by a lock nut 31. In this manner, the valve is held in uppermost position. An annular ring 32 .is screwed upon the Outer wall of the ball bearing cup 26 and is adapted to be moved over the opening 9 so as to lvary the amount of air pressure escaping therefrom.

The valve stem 11 has a reduced portion 33 upon which a quadrant sWivel. 34 is disposed and held in place by a Washer 35 and a nut 36. A tie rod 37 is adjustably secured at one end to the quadrant bya clamp bolt 38. The free end off the tie' rod is secured to a support 39 by a sWivel 40 in the manner shown in Figure 2. An elbow 41 having an opening therein in communication With an opening 42 in the valve stem is rigidly mounted upon the free end of the valve stem. A tube 43-connected to the elbow 41 at lone end thereof is in communication with an air pressure supply. A pipe line 44 is connected to each of the air passageways 10 and to a correspondmg filling mechanism 2, as shown in Figure 1.

From the foregoing description of the various parts of the device, the o eration thereof may be readily understoo The tank 1, filling mechanisms 2, bottles 3, air pressure tank 5, and cover 6 move in a circuitous path around the valve stem 11. The bottles 3 in their circuitous travel are first raised to the position shown in Figure 1. While in this position, the bottle is filled with air pressure from the tank 5 through the air passageways 10 and the pipe' lines 44. After the bottle is filled with air pressure, the liquid valve, not shown, is-opene allowing the liquid 4 to pass slowly into the bottle 3 under a pressure of 11; pound. As the liquid passes into the bottle, the air pressure therein gradually increases. The air pressure slightly accumulates, so as to temporarily retard the fiow of liquid into the bottle, the result being that the bottle is not filled fast enough. To overcome this, and at the same time, to release any unbalanced pressure in the bottle, so as to fill the bottle to the same level and prevent any foaming when the bottles are released, it is necessary to release a part of the counter air pressure in the bottle. To accomplish this, the air passageway 10, which is in communication with that bottle, will become ali ed With the opening ofthe tube 16, thus a lowing a ortion of the air pressure to escape from t e bottle through the pipe line 44, the passageway 10, the hose 22, the opening 24, and the opening 9.

The valve stem canbe turned to any desired position and rigidly held in that position by means of the clamp bolt 38. In this position, a desired vamount of air pressure will be released from each bottle as its corresponding air passageway 10 communicates with the opening in the tube 16.

In Figure 4, I have shown a bottom view of a portion of the cover 6 with the air passageways 10 therein. A valve stem 50 is passed through the cover 6, and is held in place in like manner to the valve stem 11, shown in Figure 2. A pair of arms 51 is movahly mounted upon the valve stem 50. A pair of hose 52 is in communication with the opening 53 in the valve stem 50. The free ends of the hose 52 are secured to the free ends of their respective arms 51 and in communication with the air pasageways 10. With this construction, a portion of the air can be released from the bottles at more than one osition, and at any desired point.
